1.0

Technical information bulletins (TIBs) are not official determinations made by the National Institute for 

Occupational Safety and Health (NIOSH) but are rather general working documents that provide 

historic background information and guidance to assist in the preparation of dose reconstructions at 

particular sites or categories of sites. They will be revised in the event additional relevant information 

is obtained about the affected site(s). TIBs may be used to assist NIOSH staff in the completion of 

individual dose reconstructions.

PURPOSE

In this document, the word “facility” is used as a general term for an area, building, or group of 

buildings that served a specific purpose at a site. It does not necessarily connote an “atomic weapons 

employer facility” or a “Department of Energy (DOE) facility” as defined in the Energy Employees 

Occupational Illness Compensation Program Act of 2000 [EEOICPA; 42 U.S.C. § 7384l(5) and (12)].

This TIB provides guidance on selection of (1) the appropriate International Commission on 

Radiological Protection (ICRP) organ or tissue model to estimate the internal dose for specific codes

from the World Health Organization’s (WHO) International Classification of Diseases, Ninth Revision

(ICD-9; WHO 1977), (2) the appropriate organs or tissues to estimate external dose, and (3) the 

appropriate model in the Interactive RadioEpidemiological Program (IREP). This TIB also provides 

information for selecting and assessing likely primary cancers for secondary cancers.

This TIB does not address the appropriate organ to use with medical X-ray procedures due to 

different potential exposure geometries of those procedures. The organs to be used for dose 

reconstruction from various medical X-ray procedures can be found in ORAUT-OTIB-0006, Dose 

Reconstruction from Occupationally Related Diagnostic X-Ray Procedures (ORAUT 2005), or the sitespecific technical basis documents and site profiles.

2.0

Under EEOICPA, the organs or tissues for which doses must be estimated are those that are 

delineated by the specified ICD-9 code that is received from the U.S. Department of Labor (DOL). 

While many ICD-9 codes are clear in their intended organ or tissue, additional guidance is necessary 

to identify the appropriate organs or tissues for internal and external dose estimation and the IREP 

model to use for the organ or tissue. This TIB designates the appropriate internal dosimetry organ

and tissue selection for the various ICD-9 coded cancers, the appropriate organs and tissues to 

estimate external dose, and the appropriate IREP model.

BACKGROUND

Coding of the cancers is conducted by DOL on the basis of ICD-9. The U.S. Department of Health 

and Human Services (DHHS) National Center for Health Statistics (NCHS) has issued a related 

document, International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM; 

DHHS 2008), which is widely used in the United States. ICD-9-CM is revised on an annual basis. 

Although the WHO has issued Revision 10 of the ICD, DHHS has not yet adopted it. Although the 

ICD-9-CM coding provides some additional detail that is not found in ICD-9, this has not historically 

been required for assessment under EEOICPA. However, because ICD-9-CM is widely used in the 

United States, DOL may provide some codes that did not appear in earlier versions of this TIB. 

NCHS provides a conversion table for translating a new code to its previous code (DHHS 2009). This 

table has been used to add codes to Tables 3-1 and 3-2, which appear after the text of this document. 

Due to the complexity of determining the appropriate organs for lymphatic/hematopoietic cancers, 

OCAS conducted a comprehensive review of the state of knowledge regarding the etiology and 

diagnosis of the various lymphomas, leukemias, and multiple myeloma. This TIB incorporates the 
Document No. ORAUT-OTIB-0005 Revision No. 03 Effective Date: 02/26/2010 Page 7 of 40

findings from this review as set forth in OCAS-TIB-012, Selection for Internal and External Dosimetry 

Target Organs for Lymphatic/Hematopoietic Cancers (NIOSH 2006).

3.0

3.1 SELECTION OF APPROPRIATE ORGANS, TISSUES, AND MODELS

GUIDANCE

Table 3-1 correlates ICD-9 codes to the appropriate organ and tissue selection for internal and 

external dose estimation and to the appropriate IREP model. Organs and tissues that are labeled 

“Highest non-met org/tiss” indicate that dose to the highest non-metabolic organ is to be used to 

represent the dose to the ICD-9 designated organ or tissue. A discussion of this term is included in 

Section 4.0. The remaining regions are described by the term in the Integrated Modules for Bioassay 

Analysis (IMBA) software program.

3.2 SECONDARY CANCERS WITH UNKNOWN PRIMARY CANCER SITE

Another situation that needs to be assessed is the diagnosis of a secondary cancer with an unknown 

primary cancer location. It is accepted in medicine that cancer-causing agents such as ionizing 

radiation produce primary cancers. This means, in a case in which the primary site of cancer is 

unknown, that the primary site must be established by inference to establish the probability of 

causation (POC). For each secondary cancer, the set of primary cancers that produced 

approximately 75% of that secondary cancer among the U.S. population was identified (males and 

females were considered separately). Therefore, for secondary cancers with unknown primary site, 

Table 3-2 should be consulted to select likely primary sites, which should then be evaluated using 

IREP (reproduced from Table 7 in the IREP technical documentation).

Because each secondary cancer in Table 3-2 has more than one likely primary cancer site, each likely 

primary site must be evaluated using IREP to determine a POC. If any one of the likely primary 

cancer sites yields a POC greater than or equal to 50%, this site should be assumed to be the 

originating site for the secondary cancer and should be submitted as such.

If none of the likely primary cancer sites yields a POC greater than or equal to 50%, the supporting 

documentation for all of them should be submitted, demonstrating that all of them were less than 50%.

4.0

4.1 HIGHEST NON-METABOLIC ORGAN

DISCUSSION

The dose estimate for a number of tissues is based on the highest non-metabolic organ dose, which 

is designated as “Highest non-met org/tiss” in the table. Metabolic organs are those that are 

specifically modeled by the ICRP for a particular element. The biokinetic models are based on the 

behavior of the particular element in the body, so the metabolic organs vary with the element of 

interest. The metabolic organs also include the gastrointestinal tract from ICRP Publication 30 (ICRP 

1979) and, in the case of inhalation, the respiratory tract from ICRP Publication 66 (ICRP 1994).

For radionuclides that primarily emit alpha or beta radiation, the soft tissue compartment becomes the 

primary recipient of dose. This compartment contains all the organs that are not specifically 

accounted for in the metabolic model. This compartment accounts for the dose that is delivered by 

material that is actually deposited in that tissue. An additional source of exposure to the tissue is 

known as photon cross-irradiation. Cross-irradiation is the exposure to a tissue from photons that 

originate in other tissues.
Document No. ORAUT-OTIB-0005 Revision No. 03 Effective Date: 02/26/2010 Page 8 of 40

When the energy that is emitted by a radionuclide is primarily alpha or beta radiation, the soft tissue 

compartment becomes the primary source of dose. Under this scenario most of the non-metabolic 

organs receive the same dose. For radionuclides where photon emissions are a major source of 

energy emitted, the non-metabolic organ doses can vary due to their relative proximity to the 

metabolic organs in which the radionuclides concentrate. IMBA calculates the dose from both 

sources of irradiation and sums them. For many radionuclides (predominately alpha and beta 

emitters) this causes only minor differences in doses to non-metabolic organs, so choosing the 

highest is a realistic assumption with only minor (if any) overestimation.

It is conceivable that a situation could arise in which a photon-emitting radionuclide causes a large 

difference in doses that are delivered to non-metabolic organs. In accordance with OCAS-IG-002, 

Internal Dose Reconstruction Implementation Guideline (NIOSH 2002), it is acceptable in these 

situations to base the dose on an organ that is not the highest non-metabolic organ. The choice in 

these cases should be based on the proximity of the model organ to the actual organ of interest.

4.2 MEDICAL REVIEW

Due to the complexity of determining the appropriate organs and tissues for some ICD-9 code 

cancers, a medical review by an Oak Ridge Associated Universities (ORAU) Team physician is 

required to determine the organs and tissues to use in IMBA for those cancers. These cancers have 

been designated in Table 3-1 as “Medical review.” The ORAU Team physician will recommend to the 

dose reconstructor the appropriate organs and tissues for dose estimation purposes.

4.3 THYROID OR REMAINDER SELECTION FOR EXTERNAL DOSE

For cancer sites where Table 3-1 lists “Thyroid/Remainder” for the external organ selection, there is 

no external dose model for the organ of interest and the organ is in close proximity to the thyroid. The 

thyroid has higher organ dose conversion factors than the remainder selection, which maximizes the 

dose. If a more realistic dose assessment is required rather than a maximizing dose assessment, 

then the remainder organ should be selected to calculate dose. 

4.4 REMAINDER SELECTION FOR EXTERNAL DOSE

When there are cancers of multiple organs or the cancer site is unknown, the remainder organ should 

be selected as the model to apply dose. However, if the organ location can be determined through 

the medical records or a medical review, then an organ in close physical proximity should be selected. 

The remainder selection provides an estimate of dose that is favorable to the claimant. 

4.5 BLADDER

When Table 3-1 lists “Bladder” with no modifier, this represents the urinary bladder. When the organ 

of interest is the gallbladder, “Gallbladder” is specified clearly.

4.6 MULTIPLE IREP MODELS

When Table 3-1 lists multiple IREP models for a given cancer type, the IREP model(s) to be run is 

determined based on the use of the words “OR” and “AND” in the IREP Model column.

For multiple IREP models that are connected by “OR”, only the model that best fits the actual cancer 

type should be selected and run in IREP. For example, ICD-9 code 173.0 is listed as “Non-melanoma 

skin-Basal cell OR Non-melanoma skin-Squamous cell” in the IREP Model column. The appropriate 
Document No. ORAUT-OTIB-0005 Revision No. 03 Effective Date: 02/26/2010 Page 9 of 40

IREP model would be selected and run based on the type of skin cancer (basal cell or squamous cell) 

that is listed in the claim’s NIOSH Referral Summary Document (NRSD).

For multiple IREP models that are connected by the word “AND”, separate IREP runs should be made 

for each of the listed models, and compensability is determined based on the model that results in the 

highest POC, which is favorable to the claimant. For example, ICD-9 code 233.3 is listed as “Female 

genitalia less ovary AND Ovary “ in the IREP Model column. Separate IREP runs should be made 

using each model, and compensability would be based on the model that results in the highest POC.

4.7 SKIN CANCER MODEL CLARIFICATION

When the IREP Model column lists squamous cell AND basal cell carcinomas, and the skin cancer is 

named but not clearly as squamous or basal, the non-melanoma, squamous cell model is to be used. 

This model was developed with all named, non-melanoma, non-basal cell carcinoma included.

For example, for ICD-9 code 173, if the named cancer is fibrosarcoma of skin, this is not clearly either 

squamous cell or basal cell carcinoma. It is a specific, named cancer, however, so the nonmelanoma, squamous cell model should be used (rather than using both models and selecting the 

higher POC).

The only exceptions to this rule are the named cancers basalsquamous cell carcinoma and 

squamobasal cell carcinoma. Because these are transitional forms, both IREP models should be run 

and the one that yields the larger POC should be selected.

4.8 ADENOCARCINOMA OF THE DISTAL (LOWER THIRD) ESOPHAGUS

If adenocarcinoma is indicated in the distal esophagus (also known as the lower third, abdominal, 

lower thoracic esophagus, gastroesophageal, cardioesophageal junction, or esophageal cardia), the 

appropriate IMBA, external, and IREP organ model is the stomach. To use the stomach model, both

conditions must

4.9 SECONDARY CANCERS – LIKELY PRIMARY CANCER SITES WITH MULTIPLE IMBA, 

EXTERNAL, AND IREP ORGAN MODEL OPTIONS

be met (adenocarcinoma AND correct location). If either condition is not met, the use 

of the esophagus for the IMBA, external, and IREP organ model is appropriate.

For secondary cancers with unknown primary cancer sites, the likely primary cancer sites are listed in 

Table 3-2. Because the likely primary cancer sites are listed only by ICD-9 code (three-digit code 

with no extensions), it is possible for a single likely primary cancer site to have multiple options for 

IMBA, external, and IREP organ model selection. In this case, each possible option must be 

assessed, and the option that yields the largest POC should be submitted.

For example, secondary cancer code 196.2 has a likely primary cancer site of ICD-9 code 153. ICD-9 

code 153 has an Internal Dosimetry Organ selection of ULI, LLI, and colon, depending on the 

extension of the ICD-9 code. Because it is an unknown location, each of these organs must be run 

for internal dose purposes, and the one yielding the largest dose over the exposure period should be 

selected for use in the IREP run.
Document No. ORAUT-OTIB-0005 Revision No. 03 Effective Date: 02/26/2010 Page 10 of 40

4.10 MULTIPLE SECONDARY CANCERS WITH UNKNOWN PRIMARY CANCER SITE OR 

MULTIPLE PRIMARY AND SECONDARY CANCERS

In some claims, multiple secondary cancers with unknown primary cancer locations might be 

indicated. In such cases, unless the DOL specifically states differently, each likely primary cancer site 

from each secondary cancer is to be treated separately, with individual IREP POC determinations,

and combined as separate primary cancers.

For example, consider a claim has indicated separate secondary cancers of 196.0 (Lymph nodes of 

head, face, and neck) and 197.7 (Liver, specified as secondary), with no indication of the cancers 

being metastasized from a single unknown primary cancer site. When each of the likely primary 

cancer sites is assessed, ICD-9 code 162 (Lung) yields the largest POC for each at 38% (for this 

example only). Because it is possible that each secondary cancer came from a separate likely 

primary lung cancer, the POC results for each likely primary lung cancer should be combined to yield 

a final POC of 61.56% (per multiple cancer calculation in IREP).

The same type of situation might occur when primary and secondary cancers are both indicated by 

DOL. The same logic applies that, unless specifically directed otherwise by DOL, each cancer should 

be treated as a separate cancer for the determination of POC and for combining them for the final 

POC. It should not be assumed by the dose reconstructor that any listed secondary cancer has 

metastasized from another listed primary cancer.

a. See discussion in Section 4.3

b. See discussion in Section 4.4

c. For secondary cancers, doses are assessed for the likely primary cancer site(s), which are selected using guidance in Table 3-2.

d. 42 CFR 81.30 states this cancer is nonradiogenic for the purposes of EEOICPA and assigns a POC of zero.

e. For ICD-9 code 232, if the type of cancer is specified by DOL (“Malignant melanoma or Non-melanoma skin-Squamous cell”:), use only the specified IREP 

model (note that Bowen’s disease is another name for squamous cell carcinoma in situ). If the cancer is not specified, run both IREP models as discussed in 

Section 4.6.

f. See discussion in Section 4.8

g. The external target organ should be lung if the lymphoma is known to be a B-cell variety, or thymus if the lymphoma is known to be a T-cell variety or if the 

variety is unknown.

h. For ICD-9 code 155.1, for cancers that are described as cancer of the intrahepatic ducts, select liver as the internal organ. For those that are described as 

gallbladder carcinoma, select gallbladder as the internal organ. If the description is unclear a medical review should be conducted to determine the
